I have a acer am5640 desktop. Problem started like this. The Windows suddenly became unresponsive. I turned off the PC, and tried start the PC again, it could not finish Windows startup, then I turned it off/on again, this time no beep, nothing on monitor. What seems to be the problem? Thanks

I would try to get a copy of windows 7 rather than trying to work with Vista. Vista was plagued with problems that were solved in the latest operating system offered by Microsoft. Vista was slow and heavily laden with code that required advanced hardware options to work properly.

Hi,
Well it seams like the windows CD you are using is not proper due to which the OS is not getting installed properly.
Try to install the VISTA using another CD. I am sure it will definitely fix your problem. cheers!

use windows cd to do that, reinstall it with format with new instalation mode, it will work

try safe mode. if still freezes, perform diagnose on your hard drive

Start by logging on as the Administrator so you can check the Task Manager and find out what Application or Process is monopolizing the system.

If the system is still unresponsive boot into Safe Mode. (Press F8 before the Windows startup screen appears.) If everything is fine in Safe Mode type MSCONFIG at the Command Prompt and start disabling features until you find the culprit.

Last resort, buy or borrow an external USB CD/DVD drive and use it to reinstall Windows.

Important: Reinstalling will ERASE the hard drive.

If this helps please vote for my solution.

Have the RAM checked. Or if you can do it yourself,
try cleaning the RAM as shown in the image below:


If problem persist, try another (good condition) RAM. If it works, then you'll have to replace your PC's RAM. Hope this helps.

This is commonly referred to as "The Blue Screen Of Death" because Windows promptly 'dies' when it starts showing up.

If you can get the computer to run again, back up any important files you have to CD, DVD, or a thumb drive and then reinstall windows.

i would check your power supply. take it to a local computer shop. or call acer for warranty support.

or if you are running on a backup ups, plug the computer directly into the wall and try it again

You can launch Acer eRecovery Management in a number of ways:
• By pressing the hotkey <Alt> + <F10> during the boot-up process, or at any
time when you are running Microsoft® Windows®.
This will open the Acer eRecovery Management main page.
Password
Acer eRecovery Management requires a password to activate. The default
password is six zeros (0s).
Note: If an incorrect password is entered three times, Acer
eRecovery Management closes and returns to Windows®
automatically.
System recovery
Step 1: Click on “Recovery actions”.
Step 2: You are presented with a list of available options
CHOOSE-->Recover system from CD/DVD backup
If you choose to restore from an image on an optical disk, the BIOS will be
changed to boot from the optical drive. If no backup disk is found, you are
prompted to insert the disk.
Reinstall
IF THOSE DISKS DONT WORK , YOU CAN ALWAYS RESTORE TO FACTORY SPEC FROM THE HIDDEN PARTITION ON YOUR HARDDRIVE.
Hope this helps you out .. Regards

Hello guys,
This problem would arise only when the motherboard doesn't work properly. Check with your nearest gateway service center to get your CPU work again. That would be the only thing to be done.
